ATTACHMENT FOR WHELEI) VEHICLES.

To all whom it may concern:

Be it known that I, FREDERICK D. G. COOK, a citizen of the United States, residing at Chippewa Falls, in the county of Chippewa and State of Wisconsin, have invented certain new and useful Improvements in Attachmentsfor` Wheeled Vehicles 3 and I do declare thel following to be a full, clear, and exact description" of the invention, such as will enable `others skilled in the art to which it appertains topmale and use the same.

. This inventionrelates to new and useful H improvements` in attachment for wheeled vehicles, and has `for its object to provide an attachment of this kind whereby the jar and shock incident lto the passage of the vehicle over rough .or hilly country, and particularly the shock or jar incurred by the rear wheels i, maybe practically absorbed, thus relieving the occupants of the vehicle of the usual jarring and j olting motion. `With these and other objects in View, the

*invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims. i E

`In the accompanying drawings, Figure 1 is a view in side elevation illustrating the aplication of the attachment to the vehicle; iig. 2 is a plan view thereof; Fig. 3 is a fragmentary plan view on an enlarged scale showing how the sections comprising the wheels of the vehicle.

arranged at both sides of the vehicle and `each attachment comprises a supporting `frame 2, comprising a lower longitudinally disposed frame bar 3 made in two sections 4 frames are hinged to the main axle.

` In the embodiment illustrated the numeral 1 indicates the attachment, which as shown, is arranged to take the place of the rear hinged at their meeting ends as at 5, the hinged ends ofthe lower bar of each frame being adapted to receive one end of the rear i axle 6. Each frame also comprises an upwardly curved bar 7 comprising two corresponding tubular sections 8, the inner end of one section terminating in an enlargement 8 which is received by a casing 82 carried by the inner end of the other section. A longitudinally disposedcoil spring 10 is arranged in each of said casmgs to bear against the enlargements of the first mentioned sections and to resist movement of the upper ends of the sections toward each other. Support- Specification `of Letters` Patent. Application j led August 17, v1908.

This attachment is Patented June 29, 1909.

Serial No. 448,889.

` ing wheels 1 1 of any suitable form are mounted at the forward endsof said frames, and a pair of wheels 12l mounted in the lower forked ends of suitable bearings 12 swiveled at their upper ends, as at 122, to the rear ends of the side frames. The power is transmitted to the rear axle 6, as usual, in any desired manner, and is transmitted to the front wheels 11 `by sprocket chains 13 which run over suitable sprocket wheels 14 at the ends ofthe main axle andover sprocket wheels 15 at the ends of the axles lfor the front or driving wheels. Obliquely disposed brace rods 17 are arranged between the ends of the lower frame bar of each frame and between a slidable collar 18 mounted upon the axle 6,

the fact that the lower frame bar sections are hinged at their meeting ends and further because the curved bar sections 8 are also permitted to move toward and from 'each other, it being understood that the movement of the curved bar sections 7 is resisted by the springs 10. It is also to be observed that by providing a vehicle with my improved attachment the rear drivin wheels are located considerably nearer t e front of the vehicle than would otherwise be possible and consequently the operator is able to turn the vehicle in a much smaller space.

From the foregoing description taken in connection with the accompanying drawings, it is thought that the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

I-Iaving thus described and ascertained the nature of my invention, what I claim as new and desire to secure by Letters-Patent, is rf 1. An attachment for vehicles comprising longitudinally disposed wheelsupporting side frames, each comprising two corresponding sections hinged upon the drive axle to move toward and from each other, wheels journaled to the front ends of said frames, wheel supporting bearings swiveled to the rear ends of the side frames and Wheels mounted in said bearings with means for driving the front wheels from the main axle.

2. An attachment for vehicles comprising longitudinally disposed side frames arranged at the rear ofthe vehicle and each comprising two corresponding sections hinged uponthe drive axle to move toward and from each other, resilient means tending to resist movement of the up er ends ofthe frames toward each other, wlleels j ournaled to the front ends of the side frames, wheel su porting bearings swiveled to the rear ends o the side frames and wheels mounted in said bearings with means for driving the front Wheels from the main axle.

3. An attachment for vehicles comprising longitudinally disposed side frames arranged at the rear of the vehicle and each comprising two corresponding sections hinged upon the drive axle to move toward and from each other, resilient means tending to resist movement ofthe up er ends ofthe frames toward each other, w eels j ournaled to the front ends of the side frames, wheel supporting bearings swiveled to the rear ends of said frames, wheels mounted on said bearings, means for driving the front wheels from the drive axle, collars mounted to slide upon the nesses.

drive axle, and obliquelydisposed brace rods between the collars andthe front and rear ends of the side frames. v

4. In combination with a Wheeled vehicle, side frames arranged at the rear ofthe vehicle and extending in advance and in rear of the drive axle, each of said frames comprising a lower frame bar made in two hinged sections and an upper curved bar comprising corresponding tubular sections, the end of one section 'terminating in an enlargement and the inner end of the other section carrying a casing to receive said enlargement, coil springs arranged in said casings to resist movement of the upper ends of the frame sections toward each other, supporting wheels mounted at the forward ends of the side frames, Wheel supporting bearings swiveled to the rear ends of saidV frames, Wheels mounted insaid bearings and means for driving said iirst mentioned wheelsv from the drive axle.

In testimony whereof I have hereunto set my hand inrpresence of two subscribing Wit- FREDERICK D. G. COOK. Witnesses:
